Answer 1

Answer:

=27 km/h

Step-by-step explanation:

Let the speed of truck is = x km/h

Their relative speed in same direction

(45−x)km/h (Here(45−x)

has been wrriten because bus crosses the truck which is running 150 metres ahead of it. i.e. Truck speed will be lower than that of bus)

According to the question

Time=total distancetotal speed

=150(45−x)×518=30

=150×18(45−x)×5=30

x=27 km/h

So speed of the truck is

=27 km/h
